Christina Aguilera loves showing off her cleavage and prefers to have a fuller figure.

The pop star - who shot to fame after starring on the The Mickey Mouse Club in 1993 - has had a more curvaceous body in recent years since the birth of her son Max in January 2008 but she insists she enjoys having a more bountiful body to work with.

Speaking to Lucky magazine's October issue about her new fuller figure, she said, "Actually, the challenge I've always had is being too thin, so I love that now I have a booty, and obviously I love showing my cleavage."

Christina - who had Max with her ex-husband Jordan Bratman - also urged other curvaceous women to be proud of their bodies: "Hey, if you can work it and you can own it, that confidence is going to shine through."

As well as her singing and acting talents, Christina is also a judge on the pop star search show The Voice, but she is returning to her musical roots by releasing a new album later this year. "If you love 'Fighter,' you're going to love my new album. As a woman in my 30s, I've been uncovering my independence, and it's been really fun to explore in the new songs," she told fans.
